Unit 8
discussion
People think that insurance premiums are often too high and
not worth the money, however, when an accident occurs, even something as
serious as death, a car accident, a house fire, etc. people sometimes lose everything.
Discuss with your classmates how you feel about car, life and property
insurance that you learned about in this unit. Have you had a situation where
you or someone you know did not have insurance and wish they had? Or perhaps
you were harmed by someone without insurance in some way. Do you feel this unit
helped you understand this topic better and possibly reinforce what you already
knew?
If you'd like to post a specific problem to enhance your
post, feel free. Otherwise, we are just having a regular discussion on this
topic and there are no assigned individual problems for discussion.
